smpt client for windows 7

run your windows setup (add remove programs from the control panel), there is a SMTP installation (part of IIS if I am not mistaken)

Sorry I am using windows 7 professional sp1 and checked windows features already and it does not have smtp client option

I think what you're looking for is an SMTP server (not a client, which is what you're instantiating with the .NET Framework).  Is there some reason you can't use "clinmed.gla.ac.uk" from home?

I have tried connecting to "clinmed.gla.ac.uk" but the exception i get is "Unable to connect to the remote server".

Ah, well, if you have an account at one of several free e-mail providers you might be able to use one of their servers:

hi mmalik15,

Please do check and provide the port number (default is 25, which can be omitted) in the mail server "clinmed.gla.ac.uk"  using which clients from outside the network can connect to the mail server to send mails. Because inter network mails could have been able to connect with default port, but its not publicily accessible from outsiode.
There might be a provision to send mails from outside network through some other port if provided by your company admin team. If not, you can use any public mail server as specified above.

thanks for the comments
I have tried this without any luck

  MailMessage objEmail = new MailMessage();
            objEmail.From = new MailAddress(m_EmailFrom);
            objEmail.To.Add(new MailAddress(m_EmailTo));
            objEmail.Subject = m_EmailSubject;
            objEmail.Body = m_EmailMessage;
            objEmail.IsBodyHtml = true;


           SmtpClient client = new SmtpClient("smtp.gmail.com", 25);
            client.Credentials = new NetworkCredential("myemailID@gmail.com", "xxxxxxxx");
            client.EnableSsl = true;


            client.Send(objEmail);

The exception i m getting now is


"An attempt was made to access a socket in a way forbidden by its access permissions 209.85.227.109:25"}"

I have also tried with port 587. And did try clinmed using port 25 and 587 but could not connect

Please turn off firewall and check... antivirus might be blocking..
please turn them off and check once...

windows firewall and antivirus are both disabled still no luck i have also tried telnet

C:\Users\MehtabM>telnet smtp.gmail.com 587
Connecting To smtp.gmail.com...Could not open connection to the host, on port 58
7: Connect failed

hi please check 465 port also,
Check other mail servers:

port 465 did not give an error on telnet but when tried on the we b page I got this error in the exception after few min

"The operation has timed out."

Thanks
